I am going to use it with an rx 560,so i was thinking between i7 2600 and i5 3470, the price difrence is 20 dollars.Depends what you aim is. For 60fps it still does a a decent job. For 100+ FPS it’s already not going to achieve that in more cpu heavy games.
Reducing game settings does little to reduce the cpu workload, it’s nearly all gpu related. It will actually put the cpu workload load up if the gpu starts running higher FPS.
